MECHANISM FOR MANUFACTURING DECKLE-EDGE PAPER.

SPECIFICATION forming part of Letters Patent No. 641,798, dated January 23, 1900.

Application filed May 20, 1899- Serial No. 717,588- (No model.)

To all whom it may concern:

Be it known that 1, JAMES H. REYNOLDS, a subject of Her Majesty the Queen of Great Britain, residing at Mittineague, in the county of Hampden and State of Massachusetts, have invented new and useful Mechanism forManufactoring Deckle-Edge Paper, of which the following is a specification.

My invention relates to improvements in those parts of paper-making machinery which are employed in producing feather or deckle edges on the paper; and the objects of my improvement are, first, to providea much lighter and more easily adjustible mechanism for the purpose specified above than has been used heretofore; second, to afford facilities for manufacturing either deckle or plain edge papers in a plurality of continuous strips or sheets instead of only a single'sheet; third, to insure a saving of time in adjusting the mechanism, and, fourth, to augment the cleanliness of the process. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a side View of my invention; and Fig. 2, a plan view, in partial section, of the same.

Similarfigures referto similarparts throughout both views.

Sections of an ordinary vibrating frame, sufficient to give a clear understanding of the device, are shown in the accompanying drawings. The endless-wire carrier or fourdrinier 2 is common to paper machinery and is supported upon suitable rollers mounted in a paper-machine in the usual and well-known manner, the carrier being driven'in' the direction indicated by the arrow or by the application of power in the common way. The fourdrinier, deckle-straps 5, and slices are old in the art; but the mechanism about to be described is new.

At the left of the frame 1 are the brackets 7 7, which carry the shaft Sfor the five deckle- The block 12 and the carriers 11 are provided with set-screws 13 to bear on the shaft 8 and prevent the pulleys 9 from being moved laterally, except when said set-screws are loosened. The right-hand ends of the slice-carriers 11 and 11 are supported by a secondary shaft 14, bearing in the brackets 15 15 on the frame 1. The face of each of the carriers 11 and 11 is equipped with the holder 16 to receive one end of a slice 6. Each slice 6 consists of two or more parts adjust-ably connected, so that said slice can be lengthened or shortened, and the same is capable of being raised or lowered in the holders 16.

At the right of the frame 1 are the brackets 17 17, which carry the shaft '18 for the drum 19. The five endless deckle-straps 5 pass around the pulleys 9 and the drum 19 and over the idler-pulleys 20 on the shaft 21, which is journaled in the brackets 22 22. The pulleys 20 are provided with collars and set-screws passing through the latter to bear on the shaft 21, whereby said pulleys are rendered laterally adjustable on said shaft.

The brackets 7, 15, 22, and 17 are so constructed as to be vertically adjustable either by means of the threaded collars 7, 15 22 and 17", the shanks of said brackets being threaded and adapted to engage in threaded sockets or openings in the frame 1 or through any other desirable medium.

Two of the pulleys 9 and portions of their connections are shown in section, the upper reaches of the corresponding straps 5 being omitted, and the carrier 2 is partially broken away in Fig. 2. I

The drip-tank 23 is supported on the frame 1 at the left of the drum 19 between the upper and lower reaches of the deckle-straps 5, and the scraper or doctor 24 extends from the right edge of said tank onto said drum. A pipe 25 is supported over the tank 23 by the standards 26 and 26 or some other suitable means, and said pipe is provided with perforations 27, as shown in the broken portion, Fig. 2. Water is conveyed to the pipe 25 through the pipe 28 from some source of supply.

It is obvious that more or less than five deckle pulleys and straps, with associated members, may be employed and minor changes made in the arrangement and construction of the several parts without departing from the nature of my invention. If desired, more than one shaft 21, with its idlerpulleys, may be made use of.

The operation of my mechanism is as follows: The set-screws 13 are first loosened to allow the several pulleys 9 and slice-carriers 11 and 11 to be adjusted on the shaft 8 to determine the desired width of the four bands or continuous sheets of paper which this mechanism is capable of handling, and then said set-screws are again tightened. The vertical adjustment of the several shafts is attended to and the revoluble parts set in motion. Contact between the upper reach of the moving wire -carrier 2 and the lower reaches of the straps 5 drives the latter in the direction of the arrow 1), and said straps act upon the edges of the paper, which freshly forms as the pulp on said carrier passes bebeath the slices 6, producing either a deckle or plain edge, according to the adjustment given the strap-carrying members. The adjustment mentioned above is for the purpose of separatingthe straps from the carrier sutfi ciently to allow particles or shreds of the pulpy paper to ooze between the adjacent moving members and produce what is called deckle edges,on the one hand, and to bring said members so close together, on the other hand, as to prevent feathering the edges. Vhile this mechanism is constructed especially for making deckle-edge paper, its practicability for manufacturing ordinary paper is not impaired thereby.

As intimated before, the pulp at the left of the slices 6 is divided into four continuous sheets of paper by the straps 5, when it emerges from beneath said slices and passes under the tank 23 and the drum 19 into another section of the machinery. During the progress of the paper between the straps 5 more or less shreds adhere to the same and stick to the drum 19, and it is very essential that said straps should be thoroughly cleaned at least once in the course of each circuit thereof.

To facilitate the cleansing of the straps, it is desirable to keep the drum 19 clear, and I employ the doctor 24: for this purpose,which constantly scrapes the particles from said drum when in motion and precipitates them into the tank 23. The straps themselves are cleansed directly by means of water constantly flowing over the same from the perforated pipe 25. The water from the pipe 25 washes all shreds and particles from the straps into the tank 23.

It will be particularly noted that one of the principal advantages of my mechanism over all others lies in the fact that more than one continuous sheet can be run through at the same time, an advantage which greatly enhances the capacity of my invention in the production of narrow deckle-edge paper.

I do not claim, broadly, those parts that are hereinbefore specified as old; but

\Vhat I do claim as my invention, and desire to secure by Letters Patent, is
